I enjoyed it, but did have mixed thoughts about it. It's a good "whodunit", I liked the main character, and the setting was unique, but didn't really understand the appeal of her love interest or his character in general.
One funny thing I noticed is they did a really good job of being realistic about how hacking could actually be accomplished, but on the flip side sounded like a CSI episode any time they talked about it. Like "you hack?", "my hacks are really good", "she's a top tier hacker".... etc....
